No green light on right side of mirror next to emergency button. Unable to figure out which fuse to check so I have checked nearly all of them on the left side of the dash as well as under the hood. Bluetooth phone feature does work but On-star does nothing at all.

Dealer says several hundred to "troubleshoot" before any repairs or anything which I feel is kind of ridiculous.

The front defrost-heat blower fan will not blow air until the car warms up to 180-200 degrees then the blower fan starts blowing air but then continually stops & starts intermittently. However, the rear blower fan does not seem to have a problem. Could it be a sensor or the front fan-blower be the problem?

The electrical problem happens occasionally.Had the alternator replaced, still having problems.Battery is good. Yesterday the problem escalated to lights flickering, power door locks went up and down and I even loss engine acceleration for a brief moment. I keep taking it in and they can't repeat it on demand so mechanics don't know what is wrong. Help!

What is the procedure for headlight replaceement?
